[jira] [Created] (ARROW-13388) [C++][Parquet] Add DeltaLengthByteArray

Jorge Leitão created ARROW-13388:
------------------------------------

             Summary: [C++][Parquet] Add DeltaLengthByteArray
                 Key: ARROW-13388
                 URL: https://issues.apache.org/jira/browse/ARROW-13388
             Project: Apache Arrow
          Issue Type: Bug
    Affects Versions: 4.0.1
            Reporter: Jorge Leitão


While trying to read a utf8 column with DELTA_BYTE_ARRAY encoding, pyarrow yields

`OSError: Not yet implemented: Unsupported encoding.`

It would be nice to have support for this encoding, since it lends itself really well to the arrow format, whereby values's encoding is equal to arrow's representation.
